This invention relates to rolling mills and .has special reference -to a mill for rolling packs of sheets such as are called planished `lron and 'Russia iron.

More particularly the invention relates to sheet handling mechanism for rolling mills.

One important object of the present invention is to provide an improved and novel general construction of mechanism whereby' rolls with'a minimum of labor and with great efficiency. 4

A second important objectof the invention is to provide, in such a device, a novel means for evening the sheets in thepile or pack being handled.

A third important object of the invention is to provide improved means in connection with such pack handling mechanism for separating the sheets in a pack if such sheets become stuck together.

,A fourth important object of the invention is to provide an improved gripping device for such a mechanism, the device being arranged to automatically grip the sheet pack on its return over the rolls.

A fifth important object of the invention is to provide an improved arrangement of pack gripper and means to reciprocate the same to cause the gripper to deliver a pack to the rolls, rise over the rolls and grasp the returning pack and draw it back ready for the next pass.

Vith the above and other objects in view as will be hereinafter apparent, thev invention consists' in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying, drawings and specifically claimed.

In the embodiment of the invention here shown there is disclosed a conventional pair ofroll housings 10 supporting a pair of rolls 11. These parts are those common in all such devices and are not, in their speciic construction, any part of this invention, no changes or alterations being made therein except to rovide necessary bolt, holes or other means or securing the invention proper in position: y Such rolls being old and very well nown, 1t 1s not deemed necessary to describe the same or their driving means in detail.

In front of the rolls 1s positioned a base plate 12 and across the front of said rolls extends a supporting bar 413 havin its ends rmly fixed to the housings 10. of this base 12 remote from the rolls is a pair of standards 14l and extending forwardly from these standards are longitudinal bars the line 5-5 of tthe endV l or rails 15 which have their forward ends supported on the cross bar 13 and bevelled as shown in Figure 5 to fit closely to the lower roll, 11. Adjacent the rolls these bars are provided with suitable bearin s to receive a rock shaft 16 to which is fixe a de ending rock arm 17 slotted at its lower eng to receive a pin 18 projecting from the forward part of a push bar 19 mounted on antifriction rollers 20 so that an operator, by pushing this bar with his foot, may rock the shaft 16. Tilting bars 21 are fixed on the shaft 16 just outside the rails 15. 'Each of these bars is secured intermediate its ends to the shaft so that it has a forward end normally projecting toward the space between the rolls while its rear end, provided with rollers 22, extends away from the rolls. Normally these bars lie in the full line position of Figure 5 but, to return the sheets over the top roll, are tilted b the action of the foot bar 19 to the dotted ine position of that figure. There is also fixed centrally of the shaft 16 a tilting arm 23 which projects toward the rolls and has an upwardly facing channel 24 in its forward art for purposes presently to be described.

To the rear of the rolls 11 is positioned a cross bar 25 which has its ends'secured to the housings 10. Rails 26 have their forward ends supported on this cross bar and extend rearward y and upwardly from the cross bar to a rear frame 27 which carries their rear ends. These rails are provided with antifriction rollers 28. The upper side portions of the frame 27 are connected to the housings l0 by side plates 29 having their lower edges provided with inwardly extending ianges 30.

rom a point adjacent the housings these ianges extend rearwardl in parallelism to the rails 26 but forward y and between the housings 10 these flanges are reversely curved to arch over the upper roll 11 as can clearly be seen in Figure 2. Each of the plates 29 thus extends forwardly of the rolls 11 and each of said plates has mounted on its upper forward portion a sprocket wheel 31. A shaft 32 is journalled in the frame 27 and bridges the space between the lates 29. On this shaft are fixed the sproc ets 33 which are connected by loose chains 34 to the wheels 31 respectively. A motor 35 of the reversible multispeed type drives the shaft 32 and is provided with any suitable means (not shown) for controlling its speed and direction ofmovement. Idlers 36 serve to keep the chains 34 from jumping the sprockets. Two opposite links of these chains 29 are provided each with an inwardly extending lug 37 to which is bolted the respective end of a gripper cross bar 38 supporting the gripper indicated in general in Figure 1 at 38 and specilically illustrated in Figures 7, 8 and 9. As there shown the bar 38 has mounted centrally of its underside a guide member 39,

:iframes the opening of which extends transversely of the bar to accommodate a lower gripper jaw 40. A cooperating upper gripper jaw 41 has its rear end hinged to the jaw 40 and extends over the bar 38 toward the rolls 1l. jaws are so formed that, forwardly of the bar 38, they converge so that forwardmovement of the bar 38 relatively to said jaws will spread them open as in Figure 9 while rearward movement of said bar will, if no sheets are interposed between the jaws, allow them to come together as in Figure 8. A bolt 42 extends upwardly from the jaw 4U through the jaw 41 and carries on its upper end a heavy compression spring 43 the tension of which may be regulated by a nut 44. This spring urges the jaws to closed or gripping position. While here shownv as a single bolt and spring it is obvious that two or more such bolts and springs may be provided and that the bolt and spring shown are indicative generically of a suitable means for urging the jaws to closed position. Secured on the jaw 41 just to the rear of the bar 38 is a hinge or pivot plate 45 whereto is pivoted and L-shaped dog 46 having its free end extending downwardly through an opening 47 in the jaw 41 so that it may enter a recess 48 in the bar 38 to hold said bar in jaw opening-position as shown in Figure 9. An arm 49 extends upwardly from the pivot end of this dog and is pressed by a suitable spring 50 to make certain the engagement of the dog in the recess 48 at the proper time in the operation. Across the rear end of the jaw 4() extends a cross bar 51 and springs 52 of the coiled tension type each having one end connected to the bar 51 and the other end onnectel to the llilarlS so that these springs coxlixstant y urge t e ar to grip ino' osition. hinge plate 53 is fixed forardljf) of the bar 38 to t e under side of the jaw 40 and a trig ger 54 has its lower end pivoted to the plate 53 and extends upwardly through openings 55 in the jaws 40 and 41 to project above the latter. A spring 56 is connected to the upper end of this trigger and urges the trigger forwardly. A trip rod or bar 57 has its forward end pivoted to the upper end of this trigger and, at its rear end, engages the arm 49 so that rearward movement of the trigger releases the dog and allows the bar 38 to move rearwardly relative to the jaws whereby the jaws may close and grip a plate or bundle or stack of plates.

In the operation of the device as thus far` described we may suppose that a stack of plates has just passed forwardly between the rolls and is resting on the tilting arms with the latter in their normal or horizontal position. The operator in front of the rolls then tilts the arms as in dotted lines in Figure 5 and, with his tongs, starts the pack or pile of sheets up the arms. At the same time the motor is started to bring the gripper, which lll0 weaves is open, forward over the top roll and let its lower jaw rest in the channel 24. As the pack engages the trigger'the dog is released and the gripper jaws close on the pack. The motor is now reversed and the pack moved rearwardly over the top roll until it drops on the bed rails 261 whereupon the motor is thrown into forward position so that the pack, engaged by the gripper, is forced forward to be engaged by the revolving rolls. Meanwhile the front operator has restored the tilting arms 21 to normal position. Upon the rolls gripping Well on the pack the motor is speeded upjvhich forces the bar forwardlyl faster than the pack is moving through the rolls. This causes the jaws to open and release the pack. rlihe motor is now slowed down and the dog catches the recess 48,- the latter being elongated .to give the dog time to drop. This leaves the jaws open so that further forward movement of the gripper to carry it up and over the top roll places it in position again to receive and grip the pack. A. guide 58 is slidably mounted on'the left hand end of the shaft 16 and is held in adjusted position by set screw 59. A bracket 60 is mountedvon the front of the right hand housing 10 and through this bracket slides an evener or jogger arm 61 secured in adjusted position b-y a lset bolt 62. Pivoted between its ends to the inner end of the evener arm is an oscillatable evener 63 having its upper end urged outwardly by a spring 64. On the inner face of the lower end of this evener `is awear and adjusting plate 65 which may be adjusted in yor4 out by a screw 66. A bent lever 67 is pivoted on the base 12 and has one end engaged against the plate 65 while its other end'is engaged by a rock arm 68 depending from the shaft 16. By this means one or more blows of the upper end o f the evener lever 63 may be given the pack as it is raised from horizontal to return position, it being merely necessary to tilt the tilting arms 21 up and down the desired number of times.

At the left side the rail 15 has'its forward end higher than the rear, an inclined surface 69 being provided between the two. The rail 15 at the right side is slotted and a bar 70 (see Fig. 3) is slidably mounted on this rail and is held in position by a bolt 71 passing through a downwardly extending leg 72. The forward end of the bar 70 is bifurcated and a pack opener lever 73 is pivoted in this bifurcated end and is connected by a link 7 4 with a double ended treadle 75 pivoted intermediate its ends to the lower end of the leg 72. The bar 70 is provided with a downwardly and` rearwardly inclinedv surface at its forward end and just above the rail 15 this end of the bar or slide is notched. The

surface of the opener lever is correspondefficient device of the kind described and for l the purpose specified. y
